| Outline of Final Research Achievements |
Roles of multimodal sensory cues in insects were investigated by analyzing behavioral responses to a single or conjugated cues. In Aromia bungii, the major component of the sex-aggregation pheromone released by males was identified. Female and male flight orientation led by this pheromone was enhanced by a visual factor, the color of the landing target. Using several cerambycid species, we examined whether certain objects were recognized by an adult to be either a conspecific, a mate or an enemy. Then, characteristics and functions of visual, vibratory and olfactory cues in conjugation with other cues were examined for several categories of behavior. The relative importance of each mode of sensory signal to induce or alter behavior was shown to depend on sex and the environmental and physiological conditions of the signal receiver. Our results will benefit development of effective pest control methods with a low environmental burden.

| Academic Significance and Societal Importance of the Research Achievements |
昆虫の中枢神経での情報処理メカニズムの研究が進められている。本研究で得た成果が脳・神経生理学的研究の標的，注目すべき行動指標候補の新規発掘につながる可能性がある。また昆虫は，多種感覚情報利用により環境に応じた行動遂行を可能にする情報処理システムを実装したモデルであるといえる。認知科学，ロボティクス，医療工学など関連分野との連携による今後の研究進展も考えられる。一方，昆虫の情報利用システムに関する本研究成果は，効果的で環境負荷の低い害虫防除法開発に役立つ。クビアカツヤカミキリにおける知見の一部はすでに他の研究機関においても試用されており，この侵入種の動態把握，拡散阻止への寄与が期待される。
